COOLING APPARATUS.-

Applcation filed October 6, 1922.r Serial No, 592,775.

To all whom t may concern:

Be it known that I, HnNRYwG. JANosY, ol Everett, in the county ot Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and use` lul Improvement in Cooling Apparatus, ot which the following is a full, clear, and exact description, reference being had to the accou'ipanying drawings, forming a part ot this specification in explaining its nature.

The present invention relates to a cooling apparatus or refrifrerator essentially adapted for keeping cool an article such as ice cream during its transportation by delivery truck or wagon. The cooling is eifected by a cooling fluid preferably brine resulting 'trom an admixture of ice and rock salt, and the apparatus essentially pertains to a means for circulating the brine.

The essential object of the invention is to provide an apparatus by which the cooling` fluid or brine is best conserved and its cooling iniiuence best disseminated and the escape thereof from the apparatus only allowed after it has absorbed heat and its cooling influence is no longer effective.

A further object oitl the invention is to provide an apparatus which'will combine the element of eiiiciency with simplicity of construction; an apparatus which is composed of few easily replaceable parts and one which will not easily clog and which in any event can be readily cleansed at any time. This element of clogging is one vof relative importance in apparatus 'of this nature for the circulatory systems of apparatus employed for a similar purpose are apt to easily clog and cannot readily be cleared and consequently cease to function.

The apparatus can best be seen and understood by reference to the drawings, in whichf Figure l shows the apparatus in vertical cross section.

Fig. 2 is a section on line 2&2 of F ig. l.

Fig. 3 is a section on line 3 3 of Fig. l, and

Fig. 4 is a plan of a modification.

Referring to the drawings l represents the body of the cooler. This is preferably rectangular in form with top, bottom, side and end walls all of which are insulated, being made double with a suitable insulating material 2 between them. Where the cooler is mounted upon a vehicle these insulated walls may comprise the. body of the vehicle; or the body of the cooler may be an independent structure withinl or upon the vehicle body. The insulated body of the cooler forms a casing enclosing within it the cooling chamber 3 within which the article to be kept cool is placed together also with the cooling medium or fluid and circulatory unit by which the fluid is circulated f for keeping the chamber cool. Access is had to the cooling chamber through the front of the body or casing which is provided with a removable part ordoor 4. Access is also preferably had through the top wall o'l' the casiugby means ot the ren'iovablc trap or door 5.

Arranged within the chamber of the body or casing, preferably in the extreme top part thereof, is a pan or receptacle 6 which rests upon ledges 7 projecting from the side walls of the casing. In, this pan is placed ice and salt from which the brine is obtained acting as the cooling medium. The ice and salt are placed within the pan or receptacle through the trap door 5. The pan is preterably provided with a cover 8. l

The space below the receptacle or pan. 6 forms that part of the cooling chamber where the articles to be kept cool are placed, access being had 'to this chamber through the door 4.

Located within this cooling space and in surrounding relation to the article or articles contained within it is the unit for circulating the brine.

'This unit comprises a number ot hollow plates or slabs l0.y These plates are of metal made in any suitable manner. are arranged on end standing in upright positions preferably-resting on the bottom o't the cooler and, as explained above, in surrounding relation to the article or articles contained within it.

The interposed plate and, il' desired, any or all the plates. may be provided at the bottom with a clean-out opening ll which is normally closed by a cover l2 secured in any suitable manner to the body of the plate as by screw connections 13. This opening enables the plate to be freed from sediment or other matter deposited within it and without the necessity of removing the plate or unit from the cooler.

The plates are connected at the top and bottoln by hollow connections 14. Each of these connections comprises nipples l5, 16. threaded into the respective plates and The plates y oneof the i ranged. preferably terior ofthe vint-ei-'poeedi one; of thefplahes having"thecleaning` opening. The pipe,`
